Article Salt Tolerance Potential of Selected Solanum Pennellii Introgression Lines: Unique Shoot and Root Responses(Wiley, 2025) Yildiz, Hatice Selale; Doganlar, Sami; Frary, AnneSalinity stress affects agricultural lands worldwide, causing serious yield losses. Investigation of the salinity response and tolerance mechanisms of crop plants and their wild relatives is important for developing tolerant varieties. In this study, three Solanum pennellii introgression lines (IL2-5, IL7-4-1, IL8-3), reported to be tolerant to abiotic stress, were investigated for their physiological and molecular responses to severe salinity (200 mM NaCl). The findings emphasized the variety of different responses that even highly genetically similar lines can have to stress. In IL2-5, a lack of significant root and shoot growth reduction due to salinity was associated with the up-regulation of vacuolar ion transporter genes (NHX1 and NHX3) and the lowest Na+ and Cl- accumulation in leaves, while beneficial K+ levels were preserved. In IL7-4-1, lateral root development was exceptionally strong compared to the other lines, with high Na+ and Cl- accumulation in leaves due to this unique root architecture. Despite this, the negative effects were lower on IL7-4-1's shoot growth than in IL8-3 and the control cultivar M82 due to effective reactive oxygen species management and increased superoxide gene expression. IL8-3's growth response was most similar to M82; however, it was better able to maintain beneficial K+ levels under salt stress. Overall, it was revealed that S. pennellii has multiple salt tolerance mechanisms associated with specific chromosomal segments and unique plant architecture. In addition to contributing to a better understanding of the mechanisms of salinity tolerance, these findings provide important information for increasing tolerance through targeted breeding.Article Citation - WoS: 1Citation - Scopus: 1The Current Status of Thrips Parasitoids Ceranisus (hymenoptera: Eulophidae) Species in Turkey Based on Morphology and 28s D2 Rdna(Türkiye Entomoloji Derneği, 2010) Doğanlar, Oğuzhan; Doğanlar, Mikdat; Frary, AnneThe aim of this study was to investigate genetic analysis of the species within genus Ceranisus (Hymenoptera: Eulophidae) that are interesting groups found in South Eastern Anatolia and Eastern parts of Mediterranean Region of Turkey and to compare with the other thrips-parasitoids between May 2006 and May 2007. Totally, 143 specimens (30 male: 113 female) belonging to Ceranisus genus were collected from 20 locations of 38 different localities in Hatay, Gaziantep, Adiyaman and Sanliurfa provinces. The population was divided into 13 groups based on morphologic characters. Phylogenetic relationships amongst Ceranisus species (Chalcidoidea: Eulophidae) were gathered from DNA sequence data. Fifteen species of thrips chalcid parasitoids were analyzed using one gene, D2 domain of the 28S ribosomal DNA. Among morphologically distinct 13 species/taxonomic groups, 3 of them identified as new species according to the genetical analysis. Four of the other species occurred in C. nr. lepidotus group while 5 of C. nr. bozovaensis consisted of two groups. To conclude 3 new species of Ceranisus and 3 different groups that may yield new species were determined in Turkish Ceranisus population.
